Today I am working on the fasteners at the trailing edge of the wing tip. I plan to install three nut plates. I made up another strip of 1/16" by 5/16" al and proceeded to drill and countersink for the nutplates and countersunk screws at the trailing edge. The last think I need to do is create a fastener at the leading edge.
Welcome to my builders log for Sonex S/N 767. It won't be as big as a real 767 but if you scale the speed I bet it will be almost as fast
